I like Healeo. I've tried a number of their smoothies about 1/3 of their drink menus, most of them are blended juices rather than smoothies. It comes down to your personal taste, if you get the fruit/veg that you like in it. My favorite is the one with goji.

I've gotta add Jamba Juice, it's classic for me. I don't like drinks made from powder. Acai supercharger with less ice is my fav.
